Mr. Yang's screws had no problem with the coating after zinc acid plating, but when plating a batch of spring parts, the coating of the workpiece always peeled.Because the coating quality of the workpiece is poor and cannot meet the customer's requirements, Mr. Yang does not want to lose this big customer, so he wants to look for an acid zinc plating brightener that will not peel.
Recently, when Mr. Mai used electroless nickel plating solution, the coating surface of the workpiece after chemical nickel plating is normal, but after hot water washing, the workpiece will be baked in the oven for 10 minutes, and there will be a layer of white water mist on the coating surface.Since the appearance quality of the workpiece is seriously affected, Mr. Mai asked Bigolly engineers to help solve this problem.
Mr. Zhang used the acid tin plating brightener to prepare the bath after new preparation. Although the coating color of the workpiece was uniform after tin plating according to the process parameters, the brightness was relatively poor, and the addition of brightener did not improve.What causes this?
Mr. Li is the boss of a rolling tin plating factory for electronic components.When Mr. Li's diode workpiece was tinned some time ago, due to the use of the sulfuric acid system tin plating process, the workpiece was immersed in the plating solution for a long time during the barrel plating process, which led to the glass part of the diode being corroded and could not be used normally.So Mr. Li wanted to find a tin plating additive that would not corrode the glass.
the coating of the workpiece appeared zinc explosion.The operating parameters of the plating solution are all within the normal range, and the workpiece will still appear zinc explosion after adjusting the brightener and the plating solution.Due to the serious impact on normal production, Mr. Zhang was not easy to explain to the boss, so he wanted to quickly replace an alkaline galvanizing brightener with good performance.
Recently, a batch of steel ball valve workpieces produced by Mr. Feng have been coated with 10~15 μ m thick electroless nickel coating, which is very brittle, and always cracks and falls off after bending 180 °.Since Mr. Feng did not want to lose this big customer, he was eager to find a high phosphorus electroless nickel plating solution with small coating brittleness that could meet customer requirements.
